To all whom it may concern:

Be it known" that I, KARL BRRESEN Davis, a subject of the King of Norway, residing at Fredriksstad, Norway, have mvented certain new and useful Improvements in Apparatus for Holding and Feeding Angle-Iron; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention has for its object a holdin and feeding apparatus for punching and drilling profiled iron and the like and is particularly adapted for angle iron or profiled iron comprising an angular part.

According to the invention the apparatus comprises two rollers which fit into and about an angular part of the profiled iron, and which are mounted in a frame adapted to swing on an axis, the distance of which from the two parts of the profiled iron forming its angular part is equal.

For angle iron or angular corners the apparatus comprises two rollers, one of which has a wedge-or V-shaped rim, while the other is provided with a V-shaped groove. One of said rollers may suitably be provided with driving mechanism to be actuated by hand or mechanically and this roller serves as feeding roller. 1

Besides the above mentioned apparatus the end of the profiled iron maybe carried by a clamping device mounted on a movable truck or the like and adapted to swing on an axis coaxial with the swinging axis with feeding apparatus. v

()n the drawing is illustrated a form of the invention.

Figure l is a front view of the apparatus. Figs. 2 and 3 are side views of the apparatus in two different positions, the punching machine being partly shown on Fig. 2.

Figs. 4 and 5 areend views of the movable carrier or clamping device shown in positions corresponding to the positions of the feeding device illustrated on Figs. 2 and 3. ()n Fig. 5 part of the trunk is broken away.

1 is a profiled iron and 2 a punching or drilling machine. On each side of the wifia aefi nter ta es?- punching machine is located a holdingand feeding apparatus 3 and one end of the iron beam is clamped in a movable carrier 4.

The construction of the feeding and holding apparatus is apparent from Figs. 2 and T115 apparatus comprises two rollers 5 and 6,which fit into and about an angular corner of the profiled iron between the two parts of the iron which are to be treated in the punching machine or the like. The rollers 5, 6 are mounted in a frame 7 pivoted on trunnions 8 in a stationary or movable frame 9. Trunnion 8 is located with its axis at usual distances from the two parts of the angle iron and by swinging frame 7 90 degrees the profiled iron 1 is brought into the two positions illustrated on Figs. 2 and 3, where one or other of the parts of the 1 of the profiled iron may take placeby rotating said roller.

It will be understood that the roller may also be provided with mechanical driving means.

The carrying apparatuses 4: are mounted on rails 11 on both sides of the punching machine 2 and serve to carry the end of the profiled iron, which is farthest removed from the punching machine. The carrier consists of a plvoted clamping block 12, one corner of which fits into the angular corner of the profiled iron, and two pivoted arms 13, a 14 which are adapted to be clamped against the outside of the. angle iron, one of said arms 13 ending in a screw which servesto press the other arm against the clamping block 12. Block 12 is adapted to be swung in the same manner as frame 7 on a trunnion 15 and is provided with an arm 16 for performing the swinging movement.
